Node.js is a very popular open source JavaScript runtime environment that can run JavaScript applications on the server side. It has efficient I/O operations and a lightweight memory footprint, making it popular among many companies. Let’s take a look at which companies are using Node.js in production.
- Netflix
Netflix is a well-known online video on demand service company. They make extensive use of Node.js, which they call "full stack JavaScript". Netflix’s website is written in Node.js, and they use Node.js’s built-in single-threaded event loop to handle the large number of concurrent requests. Additionally, Netflix uses Node.js to handle tasks such as communicating with Amazon AWS.
- PayPal
PayPal, a leading global online payments company, also uses Node.js to generate dynamic content. PayPal has developed a Node.js framework called Kraken, and they use Kraken to build front-end applications with Node.js as their backend. This framework allows PayPal to maintain high efficiency while maintaining code consistency and maintainability.
- Walmart
Walmart is one of the world's largest retail companies, and they need to process massive amounts of data and complete a large number of tasks in a short period of time. To address these challenges, Walmart decided to write their API service using Node.js. Node.js brings significant performance improvements and memory footprint reduction to Walmart. Moreover, Walmart also uses the Express.js framework and React.js library, which are technologies developed based on Node.js.
LinkedIn is one of the largest professional social networks in the world and they use Node.js for their backend services. LinkedIn's graph API service is written in Node.js and can interface with other services. The Node.js framework used by LinkedIn is Rest.li.
- Uber
Uber is a popular online ride-hailing company and they built their taxi dispatching system and backend services using Node.js. The efficient and lightweight memory footprint of Node.js helps Uber respond quickly while handling a large number of requests.
- NASA
NASA is an agency with a huge amount of data, and they use Node.js to process their data. NASA has adopted a variety of approaches, using Node.js with the React.js framework and the MongoDB database.
- Microsoft
Microsoft’s Cortana is an artificial intelligence assistant, and one of the technologies used in its backend is Node.js. Cortana's backend uses the extended Node.js framework Hapi.js and unites Node.js with other Microsoft technologies.
Summary:
Node.js has an increasing market share, and many large companies have chosen to use Node.js to build their applications. This is because Node.js has the characteristics of efficient I/O operations, scalability, and lightweight memory footprint. It shows excellent performance and high availability especially when processing large amounts of requests and data. The companies listed above are only some of the many companies using Node.js. As Node.js technology continues to develop and expand its application scope, we believe that more and more companies will choose to use Node.js to improve their performance. Production efficiency and service quality.

HTML and React's Integration: A Practical GuideApr 21, 2025 am 12:16 AMHTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.
React and HTML: Rendering Data and Handling EventsApr 20, 2025 am 12:21 AMReact efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.
The Backend Connection: How React Interacts with ServersApr 20, 2025 am 12:19 AMReact interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.
React: Focusing on the User Interface (Frontend)Apr 20, 2025 am 12:18 AMReact is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React in the HTML: Building Interactive User InterfacesApr 20, 2025 am 12:05 AMReact can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.
React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AMReact is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.
The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AMReact's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
